Sentinel filter bags Polyester Needlefelt

Sentinel filters bags are manufactured from pure fibers needled together to form a 3 dimensional medium. Operating on the principle of depth filtration, the fibers form a path along which the process fluid must flow.

- The sentinel material is carbon steel, zinc plated. Needle felt filter Bags which are welded. The below filter elements will fit into your existing filter housing.

Polyester Needlefelt filterbags can be operated at a maximum temperature of 110 degrees Celsius. - It is highly resistant to most alkalis and acid, organic solvents, degreasing agents and electrolytic attack. On the contrary is less resistance to aromatic, aliphatic and chlorinated solvents and UV.
